Hey dude, no idea what the yellowing is but agree with fun grown - plants look a little over watered. Not a coco guy myself (at least not right now), but I’d start with dialing back the feedings and waiting for em to dry out for a good few days. That’d be the easiest way to troubleshoot any concerns as over/under watering can often look like a number of different deficiencies. After a week or two you can then be sure if you’ve got a nute issue or an easily rectified feeding issue that’s already solved itself! Nice lookn plants dude! :facepunch:

Approaching week 4 flower- some plants developed buds, majority havent. Was asked if had any light leaks, I remember 2 separate days where the electricity tripped and messed with the timers. Cobs were on for about 10 mins each time. Or maybe my nitrogen too high? Are they reveg?:disappointed_relieved:

Hello my friend, your plants are healthy, you do a great job ! Keep in mind that each plant has her own genetic, her phenotype.. Some are starting flowering early, some doesn't show a flower before a complete month ! All you have to do is sit down and look at your garden giving you its best.. Flowers will come when they will, but for sure they will get big ! Happy growing man,! Michka

Hi homie ! You can use Bordeaux mixture (copper sulfate plus lime) it is the better non chemical fungicide I know ! Anf if you want to use Neem oil the better recipe against mildew is : sodium bicarbonate (2gr5 / rainwater) + Neem oil (a teaspoon) !

I hope It will help you , hit me fore more "grand mother" recipes/tips ! :grinning::+1:
